i am trying to compile following program and getting error due to

unable to include

path to File "mpi.h" . Is it provided under Linux kernel or we need to

download library for this

#include "mpi.h"

#include <stdio.h>

#include <stdlib.h>

/* A simple test of Reduce with all choices of root process */

int main( int argc, char *argv[] )

{

int errs = 0;

int rank, size, root;

int *sendbuf, *recvbuf, i;

int minsize = 2, count;

MPI_Comm comm;

MPI_Init( &argc, &argv );

comm = MPI_COMM_WORLD;

/* Determine the sender and receiver */

MPI_Comm_rank( comm, &rank );

MPI_Comm_size( comm, &size );

for (count = 1; count < 130000; count = count * 2) {

sendbuf = (int *)malloc( count * sizeof(int) );

recvbuf = (int *)malloc( count * sizeof(int) );

for (root = 0; root < size; root ++) {

for (i=0; i<count; i++) sendbuf

*= i;*

for (i=0; i<count; i++) recvbuf

for (i=0; i<count; i++) recvbuf

*= -1;*

MPI_Reduce( sendbuf, recvbuf, count, MPI_INT, MPI_SUM,

root, comm );

if (rank == root) {

for (i=0; i<count; i++) {

if (recvbufMPI_Reduce( sendbuf, recvbuf, count, MPI_INT, MPI_SUM,

root, comm );

if (rank == root) {

for (i=0; i<count; i++) {

if (recvbuf

*!= i * size) {*

errs++;

}

}

}

}

free( sendbuf );

free( recvbuf );

}

MPI_Finalize();

return errs;

}

Thanks
